yellowing of lower or older leaves, caused by the fungus blocking the water conducting tissue within the banana plant stem. lower leaves collapsing to form a ‘skirt’ around the plant. cut open, the stem is discoloured from yellow to red, through to dark brown or black, depending on how long the plant has been infected.
Which fungicide is best for banana?
Chlorotalonil. Chlorotalonil is a broad spectrum contact fungicide used in banana plantations to control BLSD. It can only be mixed with water as it becomes toxic to the plant when mixed with oil1 . It’s unlikely to present acute hazard in normal use.
What is the best insecticide for banana?

Banana tree leaves that are turning yellow and dying indicate that the tree is not getting the nutrients it needs. Inadequate fertilization, poor-draining soil, overwatering and fungal infection are some of the common reasons a banana tree (Musa spp.) might lack nutrients.
What is sigatoka disease?
Black Sigatoka is a leaf spot disease of banana. It is an important banana disease in many countries around the world. Severely infected leaves can die, significantly reducing fruit yield, and causing mixed and premature ripening of fruit bunches. It is not present on mainland Australia.

How do you control Sigatoka?
Management mainly involves chemical control using fungicides like copper oxychloride, mancozeb, chlorothalonil or carbendazim at the prescribed dosage. Fungicide spraying on the foliage and pseudostem should be commenced with the initial appearance and repeated at two weeks’ interval.
How do you prevent black sigatoka?
How to prevent Black sigatoka disease
- Use resistant cultivars.
- Remove or burn infected leaves or at least stack them, so the spores cannot be discharged from the lower leaves in the stack.
- Use under-canopy (drip) irrigation to reduce splash dispersal.
Is there a disease killing bananas?

First identified in Taiwan in 1990, the mould causes fusarium wilt in the Cavendish cultivar. Entering through the roots, it chokes off the plant’s energy supply, killing it from within. This fungus is a complete nightmare for producers.
